Your plan should include every step you can think of.
Here are some helpful questions to think about while you write your plan:
- What can I read about that will help me with my invention?
- Who can I talk to about solving problems and planning properly?
- What materials will I need?
- How can I control the cost of my invention?
- What steps should I follow?
- How much time should I allow for each step?
- How can I test my invention?
- How can I be sure my invention is safe to use?
